## Public functions
### aarMetadata
Added in 4.2.0
```
fun aarMetadata(action: AarMetadata.() -> Unit): Unit
```
Options for configuring AAR metadata.
### consumerProguardFile
Added in 4.2.0
```
fun consumerProguardFile(proguardFile: Any): Any
```
Adds a proguard rule file to be included in the published AAR.
This proguard rule file will then be used by any application project that consume the AAR (if proguard is enabled).
This allows AAR to specify shrinking or obfuscation exclude rules.
This is only valid for Library project. This is ignored in Application project.
This method has a return value for legacy reasons.
### consumerProguardFiles
Added in 4.2.0
```
fun consumerProguardFiles(vararg proguardFiles: Any): Any
```
Adds proguard rule files to be included in the published AAR.
This proguard rule file will then be used by any application project that consume the AAR (if proguard is enabled).
This allows AAR to specify shrinking or obfuscation exclude rules.
This is only valid for Library project. This is ignored in Application project.
This method has a return value for legacy reasons.
## Public properties
### aarMetadata
Added in 4.2.0
```
val aarMetadata: AarMetadata
```
Options for configuring AAR metadata.
### consumerProguardFiles
Added in 4.2.0
```
val consumerProguardFiles: MutableList
```
ProGuard rule files to be included in the published AAR.
These proguard rule files will then be used by any application project that consumes the AAR (if ProGuard is enabled).
This allows AAR to specify shrinking or obfuscation exclude rules.
This is only valid for Library project. This is ignored in Application project.
### multiDexEnabled
Added in 4.2.0
```
var multiDexEnabled: Boolean?
```
Returns whether multi-dex is enabled.
This can be null if the flag is not set, in which case the default value is used.
### signingConfig
Added in 4.2.0
```
var signingConfig: ApkSigningConfig?
```
The associated signing config or null if none are set on the variant dimension.
